i have a chevy blazer 1986 s-10 with a 2.6L motor and it died on me on my way home, it had a really low idle then finally it just died and when i tried to start it again it would just start and then the idle would die. i have checked for vacuum leaks and i replaced the fuel pump and alternator a while ago, what else could be the problem, if anyone could point me in the right dirction or things to test and how to fix them before i go back out there to try to fix it again i would appricate it thanks
